Sending sms in russian (utf-8) does not work

[DmitryShchegolev]

#!/usr/bin/python3

import huaweisms.api.user
import huaweisms.api.sms
import urllib

ctx = huaweisms.api.user.quick_login("admin", "admin", modem_host='192.168.3.1')
phone = "+79261234567"
message = "Тест"
result = huaweisms.api.sms.send_sms(ctx, phone, message)
print(result)

Output

UnicodeEncodeError: 'latin-1' codec can't encode characters in position 90-93: Body ('Тест') is not valid Latin-1. Use body.encode('utf-8') if you want to send it encoded in UTF-8.

To correct this issue, I change the line 111 in the file /usr/local/lib/python3.9/dist-packages/huaweisms/api/common.py. It was:

    r = requests.post(url, data=data, headers=headers, cookies=cookies, timeout=timeout, verify=verify)

I correct:

    r = requests.post(url, data=data.encode(), headers=headers, cookies=cookies, timeout=timeout, verify=verify)
